RCC Column transfers the maximum loads to the soil base directly from beams and slabs.
An entire building is complete stands on the columns of the building. To make a strong and good construction you must need to make the column properly, otherwise, it may raise construction failure. To know the steps of proper RCC column construction read the article.
This process has mainly four stages –
Step – 1
This is the very first step to construct the column. Practically the column location is decided in the field. As per the grinds of the drawing the column location is marked by lying rope.
After deciding the location, column reinforcement starts as per the structural drawing. In this step, the constructor checks the numbers and diameter of the bars. These bars are placed vertically and also check the distances between the bars and the stirrups. They also bend the hook properly.
This step is called the formwork of the column. The height of the construction floor kept 10 feet. But the concrete poured up to the bottom level of the beam if the slab is included in the beam. In construction drawing, if the beam height mentioned about 1″-6″ then column height and formwork must be 8′-6″.But the concrete dropping is not allowed more than 5 feet. This may cause segregation. So the formwork should be done within 5 feet. The casting will be done first then the rest part will be stated.
After completing the formwork, the fourth step will be started. In this step, the concrete will be poured into the column. This is done in two methods, one is manually and the other is using a machine or pump.
Important points you should follow during the concrete and after the concrete –
